6 Volt Positive Ground Regulator Wiring Diagram. Wiring diagram for 1951 COE Truck. Link to post.
A voltage regulator takes current from a battery with oscillating voltage and puts out constant voltage. System power rail to its output e. Six-volt generators and 12-volt alternators require current at voltages.
May apply to others.
In the end the alternator needs to hooked up with the battery. As you know by now your tractor was originally built with a 6 volt positive ground electrical system. The voltage regulator field. I have a 6 volt alt am I still positive ground.
